Review of menu structure

We have made changes to the game control system, and at the same time we have also reviewed the parameters related to control.

Some of these parameters, such as sensitivity and forward/reverse operation, are related to user preference, so we have made them adjustable in the setup menu.

This setup menu was originally designed with a small number of items in mind, so the menu control was changed to accommodate the increased number of items. Specifically, the menu items were changed from a flat structure to a hierarchical structure, and a tab control was introduced to accommodate this.

We will continue to adjust parameters in the new setup menu to see how we can improve the user experience.
